ISSI IS38Sx Flash Memory Devices
ISSI IS38Sx Flash Memory Devices are 1GB/2GB/4GB devices that are based on the standard parallel NAND Flash. These memory devices follow industry-standard Serial Peripheral Interface (SPI). The IS38Sx memory devices are designed to provide a non-volatile memory storage solution in systems where the pin count must be kept to a minimum. These memory devices offer an advanced write protection mechanism for data security, such as software write protection with a block lock register. The IS38Sx memory devices support write protection with WP# and permanent block lock protection command.
The IS38Sx memory devices use Single-Level Cell (SLC) technology. These memory devices feature a 100K typical program/erase cycles with internal ECC enabled endurance and 10 pages of One-Time Programmable (OTP) Flash memory area. IS38Sx memory devices operate from -40°C to 85°C temperature range.
Features
- Single-Level Cell (SLC) technology
- Architecture:
- 1bit/memory cell
- 2176 bytes (2048 + 128) page size
- Standard and extended SPI-compatible serial bus interface:
- Read: Instruction, address on 1 pin and data out on 1, 2, or 4 pins (1-1-1, 1-1-2, or 1-1-4)
- Program: Instruction, address on 1 pin and data in on 1 or 4 pins (1-1-1 or 1-1-4)
- Security:
- Blocks 7:0 are valid when shipped from the factory with internal ECC enabled
- Software write protection with block lock register, which includes BP bits (BP0/1/2)
- Hardware write protection with WP# to freeze BP bits
- Lock tight to protect BP bits during one power cycle instead of WP#
- Permanent block lock protection
